How to determine the suitable size of cable for Electrical Wiring Installation and please with Solved Examples.
Consider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a data rate of 2 Kbps (2 thousand bits/sec) which is spread to 2 Mcps
For the local oscillator you selected, what transmission frequencies could cause interference to the satellite system and how could the interference be avoided? Show a diagram.
Using 4-bit numbers to save space, multiply 3ten x 4ten in binary.
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
Resisitive load, A 4:1 step down transformer uses a 60Vac source on the primary windings.
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
Tune PI Parameters, Question: Given are the facts that Gc and Gp(s) are in series and Gp(s) = (K * Km) / [s[(Ls+R)(Js+b) + K^2m)]].
What is the BER at the output of the receiver in clear air conditions, and the average time between errors? Give your answer in years, days, or hours as appropriate. Assume an implementation margin of 0.5 dB.
Explain the term 'multiplexing' in general and describe why it is particularly important in the transmission of PAM signals and describe the main factors upon which the maximum data rate over a channel depends.
Suppose a turbine is used for generating electricity, estimate the ratio of powers generated by the same speed water and air. (Water density=1g/cm3, air density =1.2kg/m3)
Compute the Transfer Equation, The questions are for the equation: y"(t) + 6y'(t) + 34y(t) = 2x'(t) + 11x(t)
If the efficiency of the motor and drive system is 80% and it is fed through a transistor regulator at 12V, what is the mean current through this regulator when the printer is working continuously?
